Front wheel bearing VAZ-2108: dimensions, description, photo

According to the vehicle maintenance card, it is necessary to replace the front wheel bearings of the VAZ-2108. Their dimensions are larger than those of similar ones installed on the VAZ 2101-2107 model. Moreover, there are features of the replacement. The “classic” uses tapered bearings; it is imperative to observe the permissible force when tightening the hub nut. Otherwise, the bearing will fall apart and you will have to buy a new one. Eights use cylindrical bearings; when tightening the hub nut, you need to apply as much force as you can - just don’t break the thread.

Signs of a broken wheel bearing

As the vehicle is used, its components and assemblies wear out. Moreover, those that suffer the most are those that are constantly loaded - these are rubbing parts. The weight of the engine and the friction force act on the front hub bearing of the VAZ-2108. That's why its dimensions are so impressive - to cope with the load. But when an element fails, the following symptoms occur:

1. In the early stages, a barely noticeable hum appears.
2. Minor vibrations may be felt transmitted from the wheels to the body.
3. As the bearing wears, the noise and vibration increase.

If you do not replace it in a timely manner, the bearing may jam. During operation, excessive heating of the hub will be observed - there is very little lubricant inside the bearing race, the metal elements rub against each other.

Any spare part of a modern car must be perfectly matched to fit and technological dimensions. Unfortunately, the manufacturer does not always take into account the specifics of using materials in spare parts, which affects their service life, reliability, and, ultimately, traffic safety. The chassis of a car is subject to enormous loads, so it is simply impossible not to pay attention to the correspondence of the factory dimensions with the ones being replaced.

Repair tool

To replace the front wheel bearing of a VAZ-2108, you will need a tool. All work must be carried out on a well secured vehicle. You will need the following tool:

1. Set of keys and sockets.
2. Mounting blade.
3. Bearing puller.
4. Gas-burner.
5. Jack, wheel chocks and secure supports.
6. A small piece of pipe with a diameter of 10 cm.
7. Hammer and chisel.
8. Pliers for removing retaining rings.

The procedure for carrying out work on the left and right wheels is the same. It is advisable to replace bearings on both sides at once. It is required to install elements from the same manufacturer, which are recommended by the factory.

Important points

The wheel nut on the VAZ 2109 is tightened very tightly, and in addition, it is often covered with rust. It may take a huge amount of effort to move it. In such a situation, WD-40 liquid can help. If you don’t have this liquid on hand, you can generously pour oil on the nut and wait 10 minutes. Not every car owner has a wheel bearing puller at hand. In this case, to remove the bearing, you can use a hammer and a piece of steel pipe of suitable diameter (about 4.5 cm). The main thing is not to damage the inner surface of the hub with the pipe.

If scratches and gouges remain there after pressing out, the new bearing will quickly fail. When reassembling the hub, special attention should be paid to tightening the hub nut. If it is loosely tightened, play will occur, which will again lead to bearing wear.

Therefore, with a 30 socket head, you should use the longest wrench so that the force when tightening the hub nut is maximum.

Replacing wheel bearings is a procedure that every owner of a “nine” will sooner or later encounter. The only question is whether he will be ready for this. If the driver prefers to repair his car himself, then it makes sense to purchase a puller for hubs and bearings in the store. This simple tool will greatly facilitate the work and also save the car owner a lot of time and nerves.

Preparing for repairs

Now it's time to remove the old VAZ-2108 front wheel bearing. Its dimensions are indicated in the article below; when pressing out, you can use a clip from an old roller. Before starting work, do the following:

1. Loosen the front hub nut.
2. Using a 30mm wrench with a large lever, remove the nut.
3. Install wheel chocks under the rear wheels.
4. Remove the wheel bolts.
5. Raise the side to be repaired with a jack.
6. Place supports under the car.
7. Remove the wheel and place it under the car engine.

That's all, now you can start dismantling the front wheel bearing of the VAZ-2108. The dimensions of the old and new must match. If the diameter is slightly larger or smaller, the bearing may not work properly.

wwss75 › Blog › Front wheel spacers for maintenance-free bearing 2108

I rewrote it, corrected it, added it. part 1. HURRAY! It’s done, I’m holding the spacers in my hands. I have long wanted to create one for myself. It’s very difficult with a budget and purchasing via the web is no longer necessary. I couldn’t find it on sale in St. Petersburg, I heard a price tag of 2000 rubles. I contacted turners several times and was shocked by their price of about 6,000 rubles. for work. An old friend Andryukha came to the rescue. I found the time and, according to the drawing, turned it out of 45 steel, accurate to the hundredth. I didn’t take any funds :)) FRIEND! :)) I took the drawing from timur911, here is the link at www.drive2.ru/l/4438002/ In my drawing, 2 dimensions have been changed for the tightest fit of the spacer on the axle. Plus, the accuracy of production of two seating surfaces has a tolerance of 0.01-0.03 mm. (When making the inner surface, the turner makes dissatisfied faces and says that it is lazy and difficult to create) So, my version is a trial one! Everything in size will become clear after installation on the machine. I'll definitely write back. (18 months have passed, everything is EXCELLENT! Everything works! The drawing was corrected and correct 09/07/16.)

Part 2. Verification of dimensions after production during installation. The front brake disc from 2112 does not fit on the rear hub of 2108; it is necessary to grind the hub. I measured the front hub 2112 and got a fit for the disc of 58.5 mm. Since our hub has a larger fit for the brake drums, we grind the hub. The diameter is 58.5 mm on the contact side of the disc brake disc. Here, in this size, great precision is not needed; the brake disc is centered on the hub with bolts. The main thing is that he is dressed all the way to the hub. Bearing and spacer. The dimensions from the rear hub are taken as the base. 2108. This means that the installation of the bearing on our spacer must be similar. I watched a bunch of videos and articles on the web on how to remove and install the rear wheel bearing on a 2108. I also found the dimensions of these bearings and who makes them here. The diameter of the inner bearing race is exactly 30 mm. when measured with calipers 29.95mm. I identified both Russian and the latest bearings imported from other countries when I bought them from the store. The dealers also allowed me to measure the newest rear axle 2108, the size came out to be 30.01 mm. When installed, the bearing should not fit loosely on the axle, it does not have to be free-wheeling. In other words, the bearing fits tightly onto the axle (there should be no greater interference). As a base we take the control for installing the rear bearing. axles 2108.

Removing the front wheel hub

Now you need to remove the hub. To do this you will need:

1. Mark the position of the hub on the strut using a marker. Be sure to clean the surface thoroughly before doing this.
2. Using keys “17” and “19”, unscrew the nuts from the bolts securing the hub to the shock absorber strut.
3. Using a “17” wrench, you need to unscrew the lower bolts securing the ball joint to the hub. This is a simple option when you do not need to replace the ball. But if you need to change it, then you need to use a “19” key to unscrew the nut from the ball pin and remove it using a puller.
4. Completely unscrew the hub nut.
5. Carefully push the front wheel hub off the CV joint.

That's all, now you need to completely disassemble the element and remove the front wheel hub bearing of the VAZ-2108.

What parameters do factory rims have on a VAZ 2107?

For the seven, 4 bolts were used to attach the disk, and the diameter of the circle of the holes placed was 98 mm. This parameter is specified as PCD 4x98. Thus, the distance between diametrically located holes is 98 mm.

On a note! Drilling a wheel for bolts indicates not only the dimensions, but also the diameter of the disc holes. On the seven, this parameter is 12.5 mm.

Many people do not pay attention to this meaning. However, do not forget that the disc manufacturer calculates the wheel fixation of the hub with maximum accuracy, since with minimal errors, mismatches between the hub and the center of the a/d will lead to runouts.

They, in turn, can cause a tire to burst and cause a serious accident. Therefore, drilling on 2107 is carried out with millimeter accuracy.

On a note! The wheel rim on the VAZ 2107 is made for a hub with a centering hole of 58.5 mm. The hub diameter is designated as DIA 58.5. The bottom line is that large and reliable bolts do not affect the centering of the wheel to the hub. Most often they play the role of fastening elements of the flange and disk.

The centering hole helps orient the wheel product relative to the location of the hub. Therefore, if it does not coincide with the hub, it is recommended to use an adapter connecting ring.

The diameter of the wheel products on the 2107 model ranges from 13 to 15 inches, designated by the letter R. The standard wheel parameters are 13 inches (R13). Below this size is the diameter of the disc rim.

The width of wheels for sevens varies from 5 to 6 inches. As a rule, this parameter does not have the same effect as the diameter of the wheel product.

However, the width will subsequently affect the stability of the tire and wheel of the vehicle. The safety of driving a car depends on this. Full width markings for wheel 2107: 5×13-5.5×13.

Wheel offset is 15-30 mm. It represents the distance between the middle zone of the disc rim and the conjugate plane of that part of contact with the wheel hub.

Bearing removal

To remove the bearing from the seat, you will need a puller. You can even make it yourself, there are no scarce components, the design is very simple. The VAZ-2108 front wheel bearing puller is a long bolt with a coarse thread and a nut. And most importantly - spacers and mandrels with a diameter similar to that of a wheel bearing. If there is no such puller, then all the work can be done with a hammer, but there must still be a mandrel.

First of all, remove the hub itself, in which the holes are made for attaching the wheels. Next, you need to use pliers to remove the retaining rings. If you don’t have such a tool, you can use a flat-head screwdriver, pliers and an awl. After removing the rings, you can begin pressing out the bearing. If you do this with a hammer, then try to hit accurately and sharply, this way the bearing will come out faster.

Manufacturers

Many motorists do not know which VAZ-2108 front wheel bearing to choose for their car. Now you can find several manufacturers on the market:

1. GPZ-23, Vologda, has the abbreviation VBF. The plant has earned the trust of motorists and is one of the best manufacturers of wheel bearings for domestic cars. Due to the relatively low cost, these parts are practically not counterfeited.
2. SPZ, Saratov - according to many experts, the bearings of this manufacturer are the most reliable, durable and high quality. And most importantly - the very low cost of parts.
3. GPZ-20, Kursk is no longer engaged in the production of wheel bearings, but you can find products in stores and warehouses.
4. Experts do not speak very well of the Samara SPZ-3. The cost of the bearings is very low, but the quality is not great, the service life is very short.

Some auto stores try not to deal with little-known companies that produce low-quality products. Therefore, on the shelves you can only find bearings from Saratov and Vologda.

Analogs and modifications

An excellent replacement for the Russian bearing 256706 will be its imported analogue BA2B633313C. It is important to take into account the country of production of the substitute and the brand. Low-quality Chinese parts are often sold under the same markings.

In some cases, it is worth paying attention to the roller analogue 537906. This product has exactly the same dimensional characteristics, but has a much greater load capacity, although at a significantly lower operating frequency.

Such a replacement is appropriate for older VAZ models that are operated in difficult conditions. This is especially true when driving in rural areas, where load capacity is much more important than speed characteristics.

Installing a new bearing

To simplify installation, you can do a little trick - warm up the hub a little and cool the bearing in the freezer. In the first case, the metal will expand, in the second, it will contract. Pressing will be much easier and faster. The main thing is not to overheat the hub, otherwise the seal on the bearing will melt and the lubricant will leak out. As a result, you will have to buy new spare parts and do the repairs again.

Lubricate the inner surface of the hub and install the retaining ring on one side. Carefully now you can begin to press in the wheel bearing of the VAZ-2108. If the dimensions are correct and there are no deviations in the geometry of the nodes, assembly will not take much time. When finished, install the second snap ring. Assemble the entire assembly and install it on the CV joint, tightening the bolts at the top and bottom. If necessary, replace the ball joint.

The hub nut is tightened with a “30” wrench with very high force after assembling the entire suspension and installing the car on the wheels. The entire assembly is carried out in reverse order, do not forget about the marks on the surface of the shock absorber strut. After all the work, make sure that there is no significant wear on the rubber - otherwise, do a wheel alignment.

Front wheel bearing SS20 for VAZ 1117, 1118, 1119 Kalina (repair kit)

Wheel bearings are subject to extreme loads, especially on Russian roads. To ensure rotation of the car wheel without play, with minimal noise and friction, it is necessary to carefully select wheel bearings. SS20 hub bearings have passed 100% quality control and guarantee car owners confidence in road safety.

Advantages of SS20 hub bearings

• high service life and reliability of the bearing;
• quiet operation;
• long service life;
• ensure easy and silent rotation of the wheels;
• high-quality high-temperature lubricant;
• sealed ball bearings are lubricated during assembly and do not require maintenance;
• low level of mechanical losses in the bearing due to low surface roughness and high dimensional accuracy;
• comprehensive protection against counterfeiting;
• complete installation kit.

In the hub units of front-wheel drive VAZ cars, double-row ball bearings are used. During assembly, the required amount of lubricant is placed in the bearing. The internal space of the bearing is reliably sealed with oil seals, which prevents contamination from getting inside. This ensures normal lubrication of the raceways, balls and cages throughout their service life. Wheel bearings SS20 for front-wheel drive VAZ cars are maintenance-free and do not require adjustment or lubrication during operation. This approach significantly reduces the labor intensity of vehicle maintenance and at the same time ensures high reliability.

The reliability of the bearing directly depends on the accuracy of manufacturing and compliance with all standards during the production of the bearing. Therefore, for SS20 double-row ball bearings we carry out a number of additional checks, for example, monitoring the amount of axial clearance and radial “runout” in the mounted state.

The wheel bearing is one of the most heavily loaded suspension elements. Wheel bearings allow wheels to rotate and the vehicle to move as a whole. In addition to the perception of loads directly from the wheel rolling on the road, shock and thermal loads are added. Through the hub bearing, all forces arising in the contact patch between the wheel and the road are transmitted to the suspension.

That is, of the suspension and the car depends on the correct choice of front and rear wheel bearings . The main problem when replacing wheel bearings is the large number of low-quality fakes on the market that last no more than 2-3 thousand km, as well as violation of installation technology and incorrect adjustment of clearances.

Malfunctions of wheel bearings manifest themselves in the form of hum, knocking and play when the car is moving, clicks when starting and stopping. As raceways, rolling elements and cages wear, rolling resistance increases and this is accompanied by increased noise and heating of the bearings.

You can determine the malfunction of the wheel bearings yourself. To do this you need:

1. Check ease of rotation. Spin the suspended wheel with a sharp jerk and evaluate the noise level emitted by the bearing during rotation. The wheel run-out time is also estimated.
2. Determine the presence of play in the hub bearing. On a suspended wheel, applying a load with your hands in the vertical and horizontal planes, check for swing (play) in the bearing. By applying force along the axis of rotation of the wheel, you can estimate the axial clearance.

SS20 wheel bearings will help you avoid problems with low-quality spare parts. The reliability and durability of SS20 bearings is achieved through:

• accuracy of geometric dimensions in the design and production of a product;
• use of high quality steel;
• achieving the required level of surface roughness;
• use of high-tech equipment.

The manufacturing precision of wheel bearings, surface roughness and rolling elements are the key aspects that influence the level of mechanical losses in the bearing and, ultimately, determine the noise class.

During production, the service life of the hub bearings is checked selectively from the batch before failure on a stand that simulates real loads on the bearing. As part of a comprehensive quality assessment, bearing runout is checked with an assessment of the reduction in speed at two stages from 100% to 70%, and the drop in speed from the initial stage to a complete stop. At the same time, the vibroacoustic parameters of the freewheel bearing are checked.

A whole range of serious checks at all stages of the production process allows us to guarantee the buyer the high quality and reliability of SS20 wheel bearings.

SS20 hub bearings have the SS20 branding and additional protection against counterfeiting, which will provide car owners with confidence and safety on the road, and protect them from possible financial and time losses when using counterfeits.

The high quality of the lubricant ensures a service life of up to 300,000 km in the wheel bearing assembly. The amount of grease is calculated to ensure reliable lubrication of the bearings throughout their entire service life. The operating temperature range of the lubricant is from –40°С to +180°С.
